application filed August 17, 1916. Serial No. 115,563.

To all whom it may concern:

"1 Be itknown that I, Robot]? A. rnnnnn, a citizen of the Republic ofSwitzerland,

residing in Winterthur, Canton of Zurich,

Switzerland, Waldstrasse d, have invented certain new and usefulImprovements in Combustion-Engine Locomotives, of which the following isa full, true, and complete specification.

The invention relates to locomotives driven by internal combustionengines through electrical power transmission, and has for its object tosecure a smoother running motion for the vehicle and reduction of theinternal strains incident to side thrust, and also compactness andgeneral improvements in the design of the power plant as a whole. Tothis end the combustion engine plant is divided, with its two parts orhalves in parallel, and the shaft of the driven electric generatorconnected between them, instead of having the generator coupled in linewith the engine as is usual with undivided power plants.

The accompanying drawings illustrate diagrammatically carrying out ofthe invention.

Figure 1 is a side, sectional elevation;

Fig. 2 is a sectional plan;

Fig. 3 is a sectional end view; and

Figs. 4 and 5 are side and end views illustrative of an alternative formof coupling of the engine and generator shafts.

The locomotive a has as its prime motor a divided combustion engineplant comprising the halves e and 0 each plurality of cylinders havingtheir-pistons connected with parallel crank shafts f and f at a commonlevel with respect, to the vehicle frame.

The electrical transmission comprises the generator 0 and the electricmotors d and d2, of which the generator is disposed at the end of theengine halves, but in central relation thereto, its shaft. being betweenand above the crank shafts (or the proiections thereof), from which itis driven. The circuit connections of theeleciric transmission areomitted from the drawings be ing well understood.

Ii -rein the division of the plantand the r lation of its parts asshown, it results that the distance between the centers of gravity a aand s of the engine halves and the comprising a generator is muchsmaller than when the engine and generator are disposed in the customarymanner; and as shown the special advantage can be realized of bringingthese three centers of gravity approximately on a level. In this way theoscillating motions of the locomotive when rounding curves and takingswitches are reduced, there is less strain on the substructure, andtwisting of the locomotive frame is prevented. An important advantage,also, is the reduction in length and height of the entire power unit.

The crank shafts and generator shaft may be connected for driving invarious ways. As represented in Figs. 1 to 3, the ends of the crankshafts bear gears g and g which mesh with a gear g on thegenerator-shaft. Instead of this construction the three shafts may beprovided with terminal cranks h k and h of equal throw, and these cranksconnected by a coupling frame or triangular linkage i.

I claim:

1. In a combustion engine locomotive having electrical powertransmission, the combination of a divided combustion engine planthaving its halves disposed side by side, and an electric generator theshaft of which is in intermediate relation to the engine halves anddriven jointly thereby.

2. The combination ofa divided combustion engine plant the parts ofwhich are disposed with their crank shafts in parallelism, a generatorhaving its shaft in intermediate relation to and above said crank,

shafts, and means whereby the generator shaft is driven jointly by thecrank shafts.

3. The combination. of a divided combustlon engine plant having itscrank shafts in parallelism, a generator having its center of mass atapproximately vthe same height as the centers of mass of the enginehalves and its shaft in central and superior relation to thecrank-shafts, and connections whereby 5. The combination of a dividedcombus" 'tion engine plant having its crank shafts In testimony whereof,I hove signed this parallel, a generator havmg its shaft ininspecification in the presence of two W1tnesses.
